Everybody knows that the industrialized nations are the worst offenders.

I'm a filmmaker, not a scientist.

When you find something where you can give people a message and still make it an exciting movie, you get very, very excited about something. You probably even work harder than you normally do.

I think every good, entertaining movie should have a message. I really believe that, because if you do it without it, the film feels a little bit soulless.

Do not fear. Some things will never change.

When we shot "Stargate," he [ Jaye Davidson] came up to me at one point and said, "I don't like shooting movies," and I said, "Why?" "Too many people stare at me." I said, "Then you're totally in the wrong business."

Nobody makes movies bad on purpose.
